									<p>These two major loss pathways pose a threat to climate and groundwater quality while reducing nitrogen use efficiency in crop production.</p>
<p>Jingru investigated nitrogen dynamics within an integrated soil–crop–climate system, capturing variability in both space and time. Measurements of soil properties, crop nitrogen uptake, microtopography, and weather conditions were integrated to identify the key drivers of nitrogen loss.</p>
<p>The findings advance system-level understanding of when, where, and why nitrogen losses occur and support the development of more integrated and sustainable nitrogen management strategies under increasing climate challenges.&nbsp;<br><br>The PhD study was completed at&nbsp;Department of Agroecology, Faculty of&nbsp;Technical Sciences, Aarhus University.</p>
<p>This summary was prepared by the PhD student.<br><br><strong>Time:</strong>&nbsp;Thursday, 30 April 2026 at&nbsp;12:00&nbsp;<br><strong>Place:</strong> Building&nbsp;8814, room&nbsp;3075,&nbsp;Auditorium Foulum, Department of&nbsp;Agroecology, AU Foulum, Blichers Allé 20, 8830 Tjele<br><strong>Title of PhD thesis:</strong>&nbsp;<em>Spatial and Temporal Variability of Nitrogen Losses in Danish Arable Agroecosystems</em><br><strong>Contact information:</strong>&nbsp;Jingru Yin, e-mail:&nbsp;joory.yin@gmail.com, tel.: +45&nbsp;91809009<br><strong>Members of the assessment committee:</strong><br>Associate Professor Alessia Perego, Department of Agricultural and Environmental Sciences, University of Milan, Italy<br>Associate Professor Søren Marcus Pedersen, Department of Food and Resource Economics, University of Copenhagen, Denmark<br>Professor Iris Vogeler Cronin (chair), Department of Agroecology, Aarhus University, Denmark<br><strong>Main supervisor: </strong>Professor Davide Cammarano,&nbsp;Department of Agroecology, Aarhus University, Denmark<br><strong>Co-supervisor:</strong><br>Tenure Track Assistant Professor Takashi S.T.
